It seems probable that Jentink's Mits armaruhillei * from Floras is also 

 a member of this genus, bnt as the palate and teeth only of a yonng specimen are 

 figured, and not the whole skull, I am unable to be qnite certain about it. 

 Geograi)hically its inclusion in Mallotm/s is very probable, as the relatives of that 

 genus occur in Celebes and Luzon. The three genera ifallomys, l.enomi/s, and 

 CrateromifS form in fact a little group characteristic of the eastern half of the 

 East Indian Archipelago — viz. Philippines, Celebes, New Guinea, and perhaps 

 Flores. This distribution is suggestively similar to that of the llijdronv/inae 

 (Philippines, New Guinea, Australia) and of the Rh>/7whom>/inae (Philippines and 

 Celebes). 



1. Mallomys rothschildi sp. nov. 



Size large, nearly e(^ual to Cratci-omi/s schadenbergi. Fur very long and thick, 

 the woolly underfnr about 30 — 35 mm. long on the back, and the longer hairs, 

 which are comparatively few in number, nearly twice that lengtli. General colour 

 all over blackish with a silvery grey suiTusion, the wool-hairs being pale greyish 

 with either silvery or blackish tips, the very long hairs black with whitisli 

 bases. Undersurface like the underfnr of the back, greyish white, with very few 

 black hairs intermi.xed. Whiskers black. Ears short, hardly projecting beyond 

 the fnr, thinly haired, brown. Hands and feet black above ; claws white basally 

 and at their tips, brown mesially. Tail in rather bad condition, but apparently 

 brown basally and rather lighter terminally; the scales very large, and not hidden 

 by the few short hairs. 



Skull and teeth as described above. 



Dimensions of the type, an adult male, measured on the stuffed specimen, and 

 therefore only approximate : — 



Head and body (<".) 400 mm. ; tail 380 ; hindfoot Go ; ear (contracted) 'I'Z. 



Skull : basilar suture to gnathion o7'5 ; lambda to nasal tip ()3'5 ; greatest 

 breadth 30 : breadth outside m' 14, inside m' 3'o ; nasals 27 x 9 ; interorbital 

 breadth 10; palate, length from heuselion 30; diastema 21 o : palatal foramina 

 14 X u"3 ; length of upper molar series IG'3. 



Hnb. Between Mounts Musgrave and Scratchley, British New Guinea. 



The type is stuffed, in the Tring Museum. Its skull is in the British Museum. 



This fine rodent I have ventured to name in honour of Mr. Walter Rothschild, 

 by one of whose native collectors it was obtained, and to whose generosity the 

 British Museum is indebted for the donation of its skull, and also of the Fhalanger 

 next to be described. 



2. Phalanger melanotis sji. nov. 



Closely allied to I'/t. ur.sinufi Temm., but rather smaller, shorter tailed, and 

 very different in colour. Fnr thick and close, not mixed with longer black hairs 

 projecting beyond the wool-hairs. General colour silvery or hoary, becoming pale 

 yellow on the hands, feet, and furry part of tail. The hoary tone is obtained by 

 the light rings on the hairs, coppery or yellow in Pli. iirsinas, being silvery whitish, 

 and hiding the Idack of the basal jiart of the hairs much more completely, so that 

 the whole animal, instead of being black picked out with light, is light with 

 a slight indication of a darker suffusion on the body ; on the hands, feet, and
